Toynol® Superwet-4100A Wetting & Leveling Agent
Toynol® Superwet 4100A High-Efficiency Wetting and Leveling Agent
Abstract
Toynol® Superwet 4100A leveling agent is a high-performance silicone-acetylenic surfactant developed to address wetting and leveling challenges in waterborne systems. Its main functions are to powerfully lower the surface tension of waterborne systems (static surface tension reaching 24 mN/m), markedly improve substrate wetting, and provide excellent leveling. This product line is non-foam-stabilizing and VOC-free, and is suitable for a wide range of waterborne systems, from conventional coatings to advanced semiconductor processing, making it a suitable option for improving product appearance and process stability.
Key Performance Indicators
| Performance | Superwet 4100A |
|---|---|
| Static surface tension (0.3% aqueous solution, mN/m) | 24 |
| Dynamic surface tension (0.3% aqueous solution, mN/m) | 37 |
| Foam-stabilizing tendency | Non-foam-stabilizing |
| Environmental properties | VOC-free |
Main Features and Advantages
- Efficient surface-tension reduction: Markedly lowers both dynamic and static surface tension of waterborne systems, with static surface tension reaching as low as 24 mN/m.
- Excellent leveling: Improves leveling, eliminates surface defects, and yields a flat, smooth surface finish.
- Environmentally friendly and safe: VOC-free and compliant with environmental regulations.
- Process-friendly: Its non-foam-stabilizing nature avoids foam problems during production.
Recommended Application Fields
- High-performance waterborne coatings: Suitable for industrial coatings, architectural coatings, and other fields; markedly improves coating wetting on various substrates, prevents surface defects such as cratering and fisheyes, and yields excellent film appearance.
- Electronic and semiconductor materials: Used in waterborne formulations for semiconductor processing, such as cleaners and etchants; improves wetting and penetration on wafer surfaces and ensures process stability.
- Premium printing inks: Suitable for waterborne flexographic and gravure ink systems; improves ink wetting of the substrate and enhances print quality and consistency.
- Agrochemical formulations: As an agrochemical spreading and penetrating agent, enhances spreading and penetration of the spray on plant leaves and improves pesticide utilization.
- Waterborne adhesives: Improves wetting of the bonded surface, increasing bond strength and reliability.
- Metalworking fluids: Used in metal cleaning, rust prevention, and other processes; improves wetting and coverage of the working fluid on metal surfaces.
Usage and Recommended Dosage
Addition sequence: Add after the other surfactants and polymers and before pigments, fillers, and other solid materials.
Mixing: After addition, stir continuously for 15-30 minutes to ensure uniform mixing.
Special-case handling: If the viscosity rises, gentle heating can be applied; if the product solidifies or crystallizes, heating to its melting point with stirring restores it.
Recommended dosage: The typical dosage is 0.1%-0.5% of the total formulation; we recommend determining the optimal dosage through a dose-response study.
Safety and Storage
- Safety note: Wear appropriate protective equipment (such as safety goggles and gloves) during handling. On skin contact, rinse with water and soap; if it gets into the eyes, rinse immediately with plenty of water and seek medical attention.
- Storage conditions: Store sealed in a cool, ventilated, dry place, away from high temperatures and freezing.
- Packaging: 25 kg drums, 200 kg drums, 1000 kg drums.
- Shelf life: 24 months from the date of manufacture under the specified storage conditions.
Frequently Asked Questions
Q: What are the main differences between Superwet 4000 and 4100A? How should I choose?
A: The main differences are in active-matter content and surface-tension performance. Superwet 4000 has a higher active-matter content (>98%) and stronger surface-tension reduction, while 4100A offers a more cost-effective option with guaranteed performance. Choose based on the surface-tension requirements of your application and cost considerations.
Q: Does the product’s performance suffer if it solidifies or crystallizes at low temperature?
A: This is a normal physical phenomenon for this type of surfactant and does not affect performance. Simply heat it above its melting point (usually 40-50 °C), stir thoroughly until fully melted and homogeneous, and it can be used normally.
Q: Why is it recommended to add this product after the other surfactants and polymers?
A: This sequence ensures the product dissolves and disperses better in the system and avoids competitive adsorption with other components, thereby fully realizing its wetting and leveling effect. Correct addition sequence is critical to product performance.
Q: What advantages does this product offer over conventional silicone surfactants?
A: Compared with conventional silicone surfactants, this product offers stronger dynamic surface-tension reduction and better substrate wetting; its non-foam-stabilizing nature avoids foam problems during production, and being VOC-free makes it more environmentally friendly.
